Affiliate Marketing Secrets

i just don’t know what niche beer is. Can somebody explain please?

I am creating a website for students at my college. It does not contain the school name or the school logo. It is not to be affiliated with the school. Saying this, I would like to have to my school’s colors (blue and white) on my website.
Could my university react negatively to me using the school colors? Would they be able to press charges or demand my site close down?
After all, it is just a color combination, but I feel that, because it is a forum/classifieds website for students of my university, they may be more strict.
(For further explanation of my website, refer to the following example. My college is called Beer Bottle University, located in the town of Bud. The website I am creating is called Bud Students. I am not using Beer Bottle University’s logo or name, but I would like to use their school colors. Is it possible?)

the two tall men
went to the fall beach
to meet with an endearing old b-tch
in life this is not their niche
alone they sat with a cold tall beer
and a searing bold itch
not with a cute but old small dear
